Product Overview
Cooler Master developed the V-series to re-ascertain its position as a leading power supply brand. It’s based on a powerful single rail platform with outstanding voltage stability, ripple suppression and efficiency.

Thanks to a 135mm high quality FDB fan and a fine-tuned fan profile, V-series PSUs are extremely quiet, even under full load. And our brand new all black, extra slim flat-ribbon cables make cable management a breeze, enabling nice and clean builds with the best possible airflow. Features
• Fully modular cable design incorporates a single 850W +12V output that delivers up to 70A.• 80 PLUS Gold certified: up to 93% efficiency @ 50% load.• Silent 135 mm FDB fan for lower noise and longer lifespan.• Six PCI-E 6+2 pin connectors to support high-end GPUs.• 100% high quality Japanese capacitor ensures performance and reliability.• Reliable 5 year warranty.

Power-supply units, or PSUs, are an integral part of any computer build. Often overlooked, it is the component that is likely to last the longest, and it can be moved between systems when you upgrade to the latest and greatest in the future.

Conceived back in 2004 and brought to market just a year later, the 80 PLUS initiative is one of many standards introduced in an effort to increase energy efficiency in modern technology. Targeting computer power supplies, it awards PSUs that are able to achieve an energy efficiency of over 80 per cent at varying workloads and a power factor of 0.9 or more at 100 per cent load.

Very stable and quiet.Not much to say about something that just does it's job!

Quiet, efficient, fantastic ripple supresion, but not quite SuperNova G2 value.The V850 is a fantastic PSU and is built like a tank. It stays virtually silent (I say virtually as it does make noise if you put your ear against it but I'm sure few people do that), even at high loads.
The Good:
Near Silent
Fantastic ripple suppression
100% Japanese capacitors even on the modular interface board
The Average:
CPU cable design may prove awkward in SFF cases as it has no clasp to hold the two 4-pin connectors.
The Bad:
None.

Great PSU!Purchased this PSU to replace another 850w bronze psu. Choose this one for the 80 plus gold efficiency and the fully modular design. Really high quality product packaged well. Nice all black cables which makes a difference to the looks of your rig. Would highly recommend! Best PSU I've ever had!

Worked for meBought to replace a failed OCZ ModXSTREAM-Pro 600MXSP 600w PSU, it seems to have done the job successfully.
Chosen for its high efficiency and relatively large capacity as part of a workstation supporting an AMD Firepro W7000, it has proved to be a satisfyingly quiet running unit. This has a relatively large enclosure, so be sure that your case has sufficient fitting space, not only for the box itself, but for manoeuvering it into a final location.
My Tsunami Dream case, which provides for a top fitting PSU, proved to have sufficient room. But as a retrofit, I believe it would have been necessary to strip the mobo and hard drives from the case, in order to manipulate the box into position. Luckily the existing mobo was already removed for bench testing to determine which component had actually failed. So no problem if you are starting a build from scratch.
Although the upper optical drives could be left in position, it was found best to extract all their connectors and cables first. This was particularly necessary to assist with locating the modular cable connections, after placing the box, rather than beforehand. Not much finger or vision room otherwise and the cables are quite stiff to manipulate in restricted space, while pressing the connectors home.
This might not have been an issue with a more modern case, having a PSU located in the base area, where there is usually more space and access room surrounding it.
If your drives are located at the opposite end of the case from the PSU, then not all the power cables will reach past a long graphic card. Some of the cable kit supplied is longer than others. So choose accordingly.
Solidly built with a good looking finish, this pro-level PSU provides the power needed for a high-end system, without any of the flashier elements often found with units aimed at gamers. So it is good value for the high rating and fully modular functionality provided and was usefully available from Scan at a competitive price too.
Having a wallet for the left-over modular cabling is nice, but I'm not sure the neat little bag for the main PSU unit is necessary! Nice presentation when opening the packaging, but hardly needed if you don't want to carry the unit around with you!
Documentation was rather minimal. Not much of a description of connector types provided or their normal use in a PC. That is the one thing that could have been done better, as a help to newbie builders. But as it is aimed more at the pro-user, I guess the newbie market is not their intended target.
Fully recommended.
